SPECllFICATION forming part of Letters Patent N o. 656,010, dated August 14, 1900. Application filed February 16, 1900.- Serial No. 5,445. (No model.)

To a/ZZ whom, z'tmcty con/cern:

Be it known that I, CHARLES VALLER BOWLING, a citizen of the United States, and a resident of: Fulton, in the county of Calla# way and State of Missouri, have invented a new and useful Improvement lin Ch'urns, of whichthe following is a full, clear, and exact description. 4 .LA

The purpose of the invention is to provide a churn-dash VsoV constructed thatit maybe readily cleaned or turned either way with equally-satisfactory results andso that the dash will produce both agitation and aeration, which combined actionsare very desirable. The invention consists in the novel construction and combination of the severalV parts, as will be hereinafter fully set forth, and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarcharacters of reference indicate corresponding parts in all the iigures.

Figure 1 is a vertical section through a receptacle in which the churn-dash is repre-V sented in perspective and likewise illustrates a support for vthe driving mechanism of thev churn-dash. Fig. 2 is an inside View of one.` section of the churn-dash. Fig. 3 is an outer face view of the churn-dash. Fig. 4is a vertical section th iough the bottom portion of the churn-dash, the two sections being brought together; and' Fig.` 5 is a bottom plan'view'of the improved dash. l

The churn-dash A is tubular and is in two longitudinal sections l0 and 11, each ofwhich sections is transversely semicircular, and the object of constructingthe dash intwo sections is to enable the parts to be readily cleaned. The dash'may be made of any suitable material, and preferably in the upper portion of each section 10 and 1l of the dash a bloc-k 12 is secured in any suitable or approved manner, and in each block a longitudinal groove 13 is produced. The grooves of the two sections of thedash register when the sections are brought together and are adapted-to receive and clamp the upper portion of a spindle 13, which extends down into the dash any desired distance. An opening 14 is produced in each section of the dash below the block 12, secured therein, and these openings are adapted to admit air into the interiorof the dash. Each section of the dash is provided with a bottom 15, and each bottom portion 15 of the dash has a downwardly- 5 5 extending flange 16, as is vshown in Fig. 4.

jThese flanges serve to agitato. the milk as the Idash is revolved or turned from side to side.

A lower opening 17 is made in each section 10 fand 11 orf the dash just above the bottom 15, 6o

as is clearly shown in Figs. 2 and 4, and a wing or blade 18 is horizontally secured to each' section 10 and 11 of the dashjust above the lower opening 17. These wings 18 are of lany suitable shape; but usually they are wider at their outer than at their inner ends. `Each wing 18 is provided with two horizontal 'ribs 19, secured to its under face and extending downwardly therefrom, and the inner ends of the ribs 19 connect with the body of 7cthe dash, one at each side of the openings 17 in the dash.

The construction of the lower/portion of 'the dash is such that when the dash is turned lit will create a suction at the bottom of the dash; and therefore will produce a partial yvac'uumin the body portion of the dash and and through the medium of a second split band 2l, located at the top portion of the dash, the ends of the split band being tightly drawn together through the medium of a setscrew 22 or a like device.

In order to promote the agitation of the 9o milk in the receptacle 23, in which the improved dash4 may be introduced, a plate or blade 24 is located within the receptacle a suitable distance from one side and parallel with the body of the dash, and this plate or 9 5 blade 24 is usually held in position by means of a bracket 24 of any desired construction andl capable of being hooked over theupper Yedge of the receptacle 23, yas `illustrated in Fig. l1. The receptacle 23 is usually made-to loc rest upon a base 25, upon which base a frame 26 is constructed, and at the upper portion of the frame 26 the driving mechanism for the spindle 13a is located, which spindle, as

has been described, is clamped to the dash, so that when the spindle is turned the dash A is also turned. This driving mechanism may be of any suitable construction. As represented, it consists of a wheel 29, mounted to turn in suitable bearings and provided with a handle 30. A rope 3l is passed around the periphery of the wheel, and this rope is twisted around a spool 32, secured to the u pper end of the spindle 13, and the rope 3l is likewise made to pass in engagement with guide-rollers 33 at each side of the spool 32, as shown in Fig. l.

When the dash is in operation, which will cause a partial vacuum to be formed at the bottom portion of the body of the dash, the air rushing in at the upper portion of the body of the dash through the openings 14 passes downward and causes the milk or cream to be aerated while agitation is in progress, thereby combining two forces, either of which will cause the butter to be separated from the cream; but when these two forces are combined a much better result is obtained.

While the wings 18 are preferably at right angles to the body of the dash, the wings may be inclined upwardly in direction of their free or outer ends without depart-ing from the spirit of the invention.

' Having thus described my invent-ion, I claim as new and desire to secu re by Letters Patentl. A tubular churn-dash, made in two longitudinal sections and having air-inlet openings at a point near its upper end, the lower end being closed and the lower portion having openings in opposite sides, blades located above the said lower openings flanges secured to the blades and extending to the side portions of the lower openings, and a spindie clamped to the dash, substantially as described.

2. A churn-dash consisting of a tubular body constructed in two longitudinal sections,

means for securing the said sections together, each of the 'sections having an air-inlet near its upper end, the bottom portion of the sections being closed and having downwardlyextending lianges formed thereon, each'section being also provided with an opening adjacent to the bottom, a blade above each opening, and flanges secured to the under faces of the blades and extending to the side portions of the bottom openings, as and for the purpose specified.

3. A churn-dash consisting of a tubular body constructed in two longitudinal sections, a semicircular block secured in the upper portion of each section and each provided with a longitudinal groove adapted to register when the sections are brought together, each section of the dash having an air-inlet in the upper portion below the block, the said sections each having a bottom, and provided with an opening adjacent to the bottom and a blade above each opening, a shaft or spindle held in the grooves in the blocks, and means for securing the ysections of the dash together and clamping the spindle or shaft to the dash, substantially as described.

4. A tubular churn-dash made in two longitudinal sections and having air-inlet openings at a point near its upper end, the lower end being closed and the lower portion having openings in opposite sides, and blades located above the said openings, the upper ends of the sections of the dash being adapted to receive and clamp a spindle when the sections are brought together, and means for securing the sections together, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES WALLER BOWLING.
